The purpose of this study is to construct a prototype decision support system in product planning and designing. In this report, a model for determining a set of design alternatives is proposed to maximize the synthetic value obtained from multiple criteria, under cost constraint. An evaluation procedure of this model is presented by using both AHP and Additional Rate of Return Method for Compound Alternatives. The methods for treating dependency among criteria or alternatives are also given. The proposed model is newly characterized as a problem with multiple criteria under cost constraint.

Analysis of Means (ANOM) was introduced graphically by Ott(1967) as the method based on the multiple significance test for comparing independent k means. Ott(1967) discussed its use to test interaction. However, most important information for interaction in real field is not about omnibus test for interaction but about tests which can have patters of interaction. Then this paper proposed the method to test local interaction using ANOM.

This paper presents a statistical procedure for tool replacement in a two-stage metal cutting process where a workpiece is being machined by two tools, and if one of the tools fails during the cut, the workpiece becomes defective and an interruption of cutting due to excessive tool wear or sudden fracture of a cutting edge occurs. A replacement procedure is formulated from a statistical point of view. Numerical results show that the efficient tool replacement in a two-stage cutting process differs from that of a single-stage one.

In minimizing the assembly schedule for job production of the large-sized product, when all operators can be charged with all the assembly process, a serial assembly system is available, but when all operators can be used but cannot necessarily be charged with all the assembly process, a minimum necessary parallel assembly system can be added. In a study of the ease where all operators cannot be used, the system with more operators in charge is more effective in a comparison between the straight and parallel assembly systems. While in a comparison between two parallel assembly systems, the one with higher balanced schedules is more effective.

The purpose of this paper is to study the impact of environmental change to Japanese industries and to clarify the change-pattern of the activities. To analyze them, the activity is regarded as the input-output system : the former consists of capital asset and employee, the latter of value-added. The DEA method is employed to analyze them. We use not only the term of nominal value, but also of real value. The result of this study may be used effectively as the management information.

A hybrid method of a forward simulation and a backward simulation is proposed for enhancing the quality of a scheduling activity support. The importance of production scheduling in a manufacturing environment these days is first discussed, focusing on due-date conscious production such as make-to-order production and job shop production. Discussion then centers on simulation methods which are highly potential for the support. Further, reviewing the potentiality and limitation of a forward simulation and a backward simulation, a hybrid method of them is discussed and its effectiveness is shown not only on a simple jobshop model, but also on an actually working system.

BP learning algorithm from Conjugate Gradient method is an effective method for high speed learning. However, in this method, the problem of its dependency on learning initial values should be mentioned. Variable Slope is effective for learning with accuracy. Therefore, in this paper, we propose a learning algorithm that is a combination of the Conjugate Gradient and Variable Slope methods. Moreover, we propose Improved Variable Slope-Conjugate Gradient algorithm that uses the trend of Variable Slope-Conjugate Gradient algorithm. In order to verify this proposal we performed a simulation experiment using a data for the production control of a chemical plant.

This paper suggests a method for designing robotic mixed product lines as an expert system. The expert system consists mainly of the production rules for the following procedures. (1) To settle a kind of robot to be set in each work station and the position to set it. (2) To settle the position/posture of works. (3) To assign "complex elemental works" to the robots. The rules were created from the viewpoints of maximizing the efficiency of performing desired production plans and minimizing the numbers of work stations and stations for changing the posture of works.
